EWALD COUNTING MECHANISM WITH A TENS-TRANSFER May 27, 1958 DEVICE FOR CALCULATING MACHINES 3 Sheets-Sheet 3 Filed June 3, 1953 //v VENTOR 1% Un te We en 9 COUNTING MECHANISM WITH A TENS-TRANS FER DEVICE FOR CALCULATING MACHINES Harry Ewald, Eiserfeld-Sieg, Germany Application June 3, 1953, Serial No. 498,316 Claims priority, application Germany June 6, 1952 15 Claims. (Cl. 235-137) The invention relates to a counting mechanism with tens-shifting apparatus for calculating machines and the like, in which the counting wheels are, by a transverse movement, brought into and out of engagement in relation to their driving members and by the tens-shifting cams, by means of pawls, locking members are operated which render possible a movement of the tens-shifting members for carrying out the tens-shifting step of the, at the time being, next higher value place after release of the tens-shifting members by disengaging a locking bar.

The object of the invention is to construct such a counting mechanism in such a manner that, on putting a large'number of counting mechanisms in a calculating machine, the shifting members, which serve for introduc ing values into the counting mechanisms, may be given the smallest possible dimensions, so that, even in the case of machines with very many counting mechanisms, owing to the small masses to be moved, an absolutely accurate calculation is guaranteed. According to the invention, this is achieved by reason of the fact that the tens-shifting members and pawls are arranged in such a manner in the direction of the transverse movement of the counting wheels, between the latter and the locking members and the locking bar, that the tens-shifting apparatus is fitted in a narrow frame, the Width of which is not substantially greater than the diameter of the counting wheels.

An example of embodiment of the invention is repre sented in the accompanying drawings, in which:

Fig. l is a perspective view of the counting mechanism;

Fig. 2 is a front elevation of the counting mechanism;

Fig. 3 is a rear elevation of the counting mechanism;

Fig. 4 is an elevation of the left-hand side of the counting mechanism;

Fig. 5 is an elevation of the right-hand side of the counting mechanism;

Fig. 6 is a section through the counting mechanism with the set of counting Wheels in the position of rest;

Fig. 7 is a section through the counting mechanism with the set of counting wheels in the calculating position; and

Figs. 8 and 9 are two further sections through the counting mechanism.

In the perspective View of the counting mechanism shown in Fig. 1, the counting wheels are, in order to render the individual parts of the tens-shifting device more clearly recognisable, represented comparatively widely spaced apart. In addition the counting wheel of the lowest value place is shifted through a further amount from the adjacent counting wheel. In this Way also, the clarity of the representation has been improved.

The counting mechanism is fitted in a frame which consists of two-side plates 1 and 2 which are held together by a base plate 3 and a connecting plate 4. The counting wheels 5 are arranged on an axle 6, the ends of which project through slots 7 and 8 in the side plates 1 and 2 and are guided in them. 9 are the tens-shifting cams of the counting wheels 5. Co-operating with the tens-shifting cams 9 are pawls 10 which are mounted on an axle 11. The axles 6 and 11 are fixed in a separate frame which consists of two plates 12 and 13. The plate 12 has grooves 14 which serve for guiding the pawls 10. In the same way, the plate 13 also has grooves 15 for guiding the pawls 10 (Fig. 3). The bent-over side parts of the plate 13 have, in their bottom part, guiding slots 16 and 17 (Figs. 8 and 9), with which they overlap an axle 18 which is fixed in the side plates 1 and 2, sothat the frame, which is formed by the plates 12 and 13 is faultlessly guided on the engagement and disengagement of the counting wheels 5.

' The pawls 10 are pulled, by springs 19, into their position of rest represented in Figs. 6 and 7, in which the outer end of the upper arm of each pawl 10 fits in the corresponding groove 14 in the plate 12. The downwardly extending arms of the pawls to co-operate with locking members 20, the lower arms of the pawls being formed in such a manner that they remain in the position of readiness for operation, opposite the locking members on the engagement and disengagement of the set of counting wheels 5. The locking members 23 are mounted on an axle 21 and are pulled into their locking position by tension springs 22; The locking members 20 serve the purpose of locking tens-shifting members 23 in their position of readiness, a shoulder 26a of each locking member 20 engaging in front of a bent-oil part 24 of the lower arm of the corresponding tens-shifting member 23. The tens shifting members 23 are mounted on the axle 18 hereinbefore mentioned, which is fixed between the side walls 1 and 2. Tension springs 25 tend to rotate the shifting members 23 in the direction of a tens-shifting movement; Instead of a tens-shifting member 23, there is provided, for the counting wheel 5 of the lowest value place, a stationary setting lever 26 which, like the tenssnifting members 23, is mounted on the axle 18, but, with its bottom fork-shaped end, engages the axle 21 on which the locking members 20 are mounted and i thus secured in its position.

Also mounted on the axle 21 are two plate-like arms 27 and 28, between which a locking bar 29 is fixed. The locking bar 29 has, beneath the shoulders and of the locking members 20, recesses 30, the width of which corresponds to the width of the locking members. By means of a spring 31, the locking bar 29 is pulled upwards into its locking position (Fig; 7), in which the recesses 30 engage the shoulders Ztla of the locking memers 20, so that the parts of the locking bar 29, which lie between the recesses 3% lie in front of the bentofi? parts 24 of the tens-shifting members 23. The ar-. rangement is such that, when the locking bar 29 is in its locking position (Fig. 7), the bent-off parts of the tensshifting members are at a small distance from the locking bar 29. For controlling the movement of the locking bar 29 there is used a downwardly extending part. 32 (Figs. 1 and 2), which is provided on the plate 13 of the frame of the set of counting wheels 5 and which on the disengagement of the set of counting wheels 5, meets the plate-like arm 27 of the locking bar 29 and rocks the latter out of its locking position. Since the frame of the set pr counting wheels 5, which is formed of the plates 12 and 13, is moved upwards on the engagement of the set of countingwhcels, it follows that the locking bar 29 arrives into its locking position on the engagement of the counting mechanism and is again rocked back onthe disengagement of the counting mechanism.

The following device is used for returning the tens:

which projects through an opening in the side wall 2, with 7 another lever 37 of the first order, which is rotatably mounted on the outer end of the axle 18. Engaging the free arm of the lever 37 is a spring 38 which tends to pull the lever 37 into its position of rest in which the returning bar 33 and the front connecting plate 4 lie (see Figs. 8 and 9). In this position, the Z-shaped returning bar 33, which is provided in its bottom part with correspond ing grooves, serves as a comb-like guide for the tens shifting members 23. For guiding the tens-shifting members 23, there is also provided a guiding rail 39 which is provided with corresponding recesses and which is fixed to the front connecting plate 4 by means of rivets or the like.

Mounted on the lever 37 is an escaping pawl 40 which is pulled into its position of operation, which is fixed by a stop 40a, by a spring 41. The escaping pawl 40 can, as can easily be seen from Fig. 1, be swung back in the counter-clockwise direction without the lever 37 being affected. However, when the deflecting pawl 40 is swung in the clockwise direction then, since the stop 4011 does not allow a rotation of the pawl 40, the lever 37 and, consequently, the return bar 33 are shifted.

The following device is used for engaging and disengaging the set of counting wheels 5. Acting on the ends of the axle 6 of the set of counting wheels 5, which ends project, on both sides, through the slots 7 and 8 of the side plates 1 and 2, are two connecting rods 42 (Fig. 4) and 43 (Figs. 1 and 5), of which the connecting rod 42 is hinged to a crank 44 (Fig. 4) and the connecting rod 43 is hinged to a plate 45 (Figs. 1 and 5). The crank 44 and the plate 45 are fixed on an axle 46 which is rotatably mounted in the side plates 1 and 2. The plate 45 carries a crank pin 47 (Figs. 1 and 5), which is advantageously provided with a roller. Suspended at the lefthand end of the axis 6 is a lug 48, which is acted upon by a spring 49 (Figs. 2 and 4), which tends to pull the axle 6 of the set of counting wheels 5 downwards and thus to disengage the set of counting wheels 5. The connecting rod 42 has, in its upper part, a recess 50 which engages an octagonal plate 51 (Fig. 4) which serves for limiting the disengaging movement of the counting mechanism. The octagonal plate 51 is mounted eccentrically on a screw bolt and it can be fixed in its various positions by a nut 52.

On the side plate 2 there are provided two bolts 53 and 54 which carry a rail 55 on which a slide 56 is guided (Figs. 1 and 2). The slide 56 has a stud 57 which is connected with an engaging linkage (not shown) for the counting mechanism. n the slide 56 there is provided a controlling cam 58, which is provided with an oblique surface and which co-operates with the escaping pawl 40, hereinbefore mentioned, of the lever 37. The slide 56 also has an oblique surface 59 which co-operates with the crank pin 47 of the plate 45.

The operation of the counting mechanism and the tensshifting device described is as follows. When the counting mechanism is to be engaged, the slide 56 is moved downwards by means of the linkage (not represented) which acts on the stud 57. The crank pin 47 is thus first forced aside by the oblique surface 59 of the slide 56 and the plate 45 is thus swung in the counter-clockwise direction. In this way, the crank 44 is correspondingly swung by means of the axle 46 and thus the axle 6 of the counting wheels is moved upwards by means of the connecting rods 42 and 43, so that the set of counting wheels 5 comes into engagement with the amount-shifting mechanism of the machine. On the further downward movement of the slide 56, the crank pin 47 slides on the side surface of the slide 56, which surface extends parallel to the direction of sliding, so that no further shifting of the crank pin 47 takes place. However, at the same time, the escaping pawl 40 is affected by the controlling cam 58, the controlling cam tending to swing the pawl 40 in the clockwise direction. However, since the stop 40a of the pawl 40 rests on the lever 37, such a rotation of the pawl 40 is impossible; on the contrary, the lever 37, which carries the pawl 40, is swung in the clockwise direction (Fig. l) by the controlling cam 58, the lever 35 (Figs. 1 and 9) and the lever 34, which is connected with it through the returning bar 33, being correspondingly rocked by means of the bolt 36.

' The returning bar 33 is thus moved towards the tensshifting members 23, the latter being moved back into their position of readiness if they had not been shifted as a result of a previous tens-shifting operation. The return movement of the tens-shifting members 23 is so large that the bottom bent-off parts 24 of the tens-shifting members arrive in front of the shoulders 20a of the locking members 24 so that the locking members 20 can fall into their locking position under the action of the springs 22. On the further downward movement of the slide 56, the pawl 40 slides off the controlling cam 58, so that the lever 37 snaps back into its position of rest under the action of the spring 38, with the result that the returning bar 33 again arrives into its position of rest.

On the preceding upward movement of the axle 6 of the set of counting wheels 5, the frame, which consists of the plates 12 and 13, is also moved upwards, so that the downwardly extending part 32 of the frame plate 13 releases the plate-like arm 27. The arm 27 is therefore pulled upwards by the spring 31 and thus brings the locking bar, which is fixed between it and the arm 28, into the locking position. The movement of the locking bar 29 is limited by downwardly extending parts of the arms 27 and 28 meeting the axle 46. In its locking position, the locking bar engages, with its recesses 30, the forwardly extending arms of the locking members 20 and consequently lies, as hereinbefore explained in front of the bent-01f parts 24 of the tens-shifting members 23.

At the same time as the axle 6 of the set of counting wheels 5 the axle 11 which carries the pawls 10 will also have been moved upwards. However, the correspondingly long arms of the pawls 10, which arms extend downwards, then remain in readiness for operation, so that, by shifting one of the pawls 10, the corresponding locking member can be swung back.

Now, if, on introducing the numerical values into the individual value places of the counting mechanism, one of the counting wheels 5 is shifted beyond the place that corresponds to the digit value "9, the tens-shifting cam 9 of the wheel 5 effects a swinging back of the pawl 10 concerned. The pawl 10 then presses, with its downwardly extending arm, against the upwardly extending arm of the corresponding locking member 20, so that the latter is swung back from its locking position. The shoulder 20a of the locking member therefore releases the bent-off part 24 of the tens-shifting number 23 associated with it, so that the tens-shifting member 23 carries out a small rotation under the action of its spring 25, its bent-off part 24 meeting the locking bar 29. The tens-shifting member 23 is thus prevented by the locking bar 29 from carrying out a still further move ment.

After the calculating operation, the counting mechanism is again disengaged, the slide 56 being again pushed back into its upper position of rest. On this movement, the pawl 40 deflects the controlling cam 58 of the slide 56 without the lever 37 and, consequently, the returning bar 33 being affected. Towards the end of the returning movement of the slide 56, the crank pin 47 of the plate 45 slides off the side face of the slide 56 over the oblique surface 59, so that the axle 6 of the set of counting wheels 5 is again lowered by means of the connecting rods 42 and 43. On the downward movement of the set of counting wheels 5, the individual counting wheels come into engagement with the tens-shifting members 23, the counting wheel 5 of the lowest value place coming into engagement with the setting lever 26. At the same time, the plate-like arm 27 is swung down in opposition to the action of the spring 31 by the downwardly extending part 232 of the plate 13, which, together with the plate 12, forms a frame, and the locking bar 29 is thus swung back from its locking position. The locking bar 29 thus releases the bottom bentolf parts 24 of those tens-shifting members 23 which were released by locking members 10, so that the tensshifting members 23, the locking members of which have been released in the manner hereinbefore described, can carry out their tensshifting movement. These tens shifting members 23 thus carry out the shifting movement under the action of their springs and introduce the units, that are to be transferred, into the corresponding value places of the counting mechanism. If a counting wheel 5 is then moved from the position 9 into the position 0, the tens-shifting cam of the counting wheel 5, by means of the associated pawl 10 releases the locking member 20 for the tens-shifting member 23 of the next higher value place. Since the locking bar 29 is no longer in its locking position, the released tens-shifting member 23 can at once carry out the tens-shifting operation under the action of its spring 25. In the manner described, a tens-shifting operation passing from the lowest value place to the highest value place of the counting mechanism is possible.

The return of the tens-shifting members 23 into their position of readiness is effected when the counting mechanism is again engaged on a subsequent operation. The returning bar 33 is then operated in the manner hereinbefore described by the controlling cam 58 of the slide 56 by means of the pawl and the levers 37 and 35, so that the shifted tens-shifting members 23 are shifted back.

On total-taking operations of the machine, the counting mechanism is engaged in a manner similar to that of the case of addition operations of the machine. However, the counting wheels 5 are, in the total-taking operation, rotated in the opposite direction, so that the tensshifting cams 9, in this case, meet with their radially extending flanks the correspondingly arranged stop surfaces of the pawls it and the counting wheels 5 are therefore kept in their zero position.
